maybe, maybe not. If the footage changed a lot, you might get an over estimate as you’d have even more motion than the actual piece – which can effect the compression process and therefore the file size.
But, Steve, you’re point is taken – you can probably get an average and guess based on that. And for these purposes it’s probably good enough.
For the record, Edward, compressing in AE is a very bad way to go. It isn’t designed for the purpose of compressing, and while it can do it, it does a poor job compared to actual compression apps. File size will be bigger and look worse when compressed out of AE.

Oh, and I should point out that if you are rendering a section to help guess, choose a section that is most like the whole piece – if there is a lot of motion in it, and you render the first 10 seconds which are slow and unchanging, you will get skewed results.

unless you’re rendering uncompressed, which is the same size every time, that6 file size will vary a lot based on content.
QT Animation, for example, really varies across the board depending on what’s in the video. I’ve had text on a solid BG come in close to ther same size of a sorenson 3 compressed video.
If you’re talking sorenson 3, again, you can set a limit for the data rate, but that’s an estimate. It will sometimes go over, and often come in under the limit.
So yeah – I guess you can guess-timate, but there is no real way to make sure, as far as I know.

That depends what you mean – you can tell after effects to break up your render – in other words, you can say, for example, if you reach 2 GB, then stop here, and render the next 2 Gb as a separate QuickTime file. (Under: Preferences > Output)
On the other hand, if you want to know if it’s possible to to make the complete rendered video constrain to a specific file size (so it just renders and targets a specific size for the whole movie) then no.
Or at least, to my knowledge, no.
You have to render uncompressed, and then use a compression program with the ability to constrain video to certain file size. Sorenson Squeeze can do this.

wait – are you on a 64 Bit OS or not?
Because natively, AE will not see all 4 GB on a 32-Bit OS. However, it will use the extra RAM during RAM previews and renders if you enable multi-processing, because it basically opens up invisible instances of AE in the BG, and those instances will use the extra RAM.

Oh, and Trapcode Particular is probably the way to go here, as far as particles go…

OK, it actually seems fairly simple – but I have to admit it happens so quickly, and there are no controls to make it rewind — that this is all based on a quick glance.
Part of this was probably done in a 3D app, but I think you can get comperable results in 2D. A particle system was used to generate the grid of logos that at first stay still but then move out into Z space towards the camera.
The partcles were used as a matte for the original footage – so basically, they probably had a setup like this:
1. Footage
2. Particles
3. Particles
4. FootageSo, they had the full footage on top, below that, the particles, below that a nother copy of the particles, and below that, a duplicate of the footage.
The bottom footage (4) uses the particles (3) as an alpha map. The top particle (2) had an opacity of 0 to start.
They did a linear wipe of the top footage, to reveal the particle matted footage (3,4) below it. as the particles moved towards the camera they faded on the top particles so that the color of the particles appears to change from the footage colors to the blue particles.
Alternatively, they may have actually done a linear wipe on of the blue particles so that it fades from footage colors to blue from left to right. Nothing personal, but I watched this twice, and without player controls, I don’t feel like watching it a 3rd time to be sure.
Hope it helps.

watch this tutorial:
https://library.creativecow.net/articles/rabinowitz_aharon/outline.php
then, maybe use the keyed actor as an inverted alpha matte for the outline layer?

Or, if your using CS3, you might try using the layer style called Stroke (like in photoshop) and then set the layer style blending options property called “Fill Opacity” to 0. THat will leave the stroke, while hiding the image.
You may need to pre-comp the keyed layer before doing that.
